GEARING.

To all iU/iom t may Concern.'

Be it known that l5 AUGUST H. Lnirnirr, a Y citizen of the UnitedStates, residing in' the borough of Queens of the city of Neiv- Yorl, inthe State of New York, have invented certainlneiv anduseful improvementsin Gearing, of Which the following Yis a specification,V reference beinghad to the accompanying drawing, forming a. part hereof. Y

This invention is concerned primarily with improved gearing in which,Where more than one gear or other part is carried'on a shaft, there .isa gear integral with the shaft More particularly, the immediate problemhas arisen in double reduction gearing in which tivo gears are carriedvon a shaft in close juxtaposition to eachother, these gears being ofdifferent diameters to afford the desired reduction.

' The improvement will appear in greater detail hereinafter inconnection with the description given with reference to the Villustratedembodiment in the drawing in Which the single `vieiv shows partly insection and partly Vin elevation a shaft and double redurtion gearing. YY The immediate prohlemlias arisen in autoniohile practise Where thereis desired a Compact construction and relation of parts at the rear end'for the purpose ofr'ibtaining a double reduction. As shown inY the-draivi (i. a spur pinion o is formed integral with the pinion shaft onwhich is rarried a bevel rin` gear c secured by bolts @"to a flange d ofits'liiih d. The elements thus far described in their intendedrelationship ivill have the huh d ofthe bevel Oear o in lesejuxtaposition to. ann, usually` in abutment with the spur pinion ff. Thehuh d is shown yshrunk on tothe shaft key o being prefer` ably employedas a supplemental holding element. The inner face ofv the hub d may"flange and resting Specification of Letters Patent.

abut against the proximate face of thev pinion a. As a final safeguardin fixing the `hub d" securely on the shaft a loc'knut f maybe threadedon to the `shaft Zi against the hub d and finally locked in place bymeans of of a look Wire g encircling the nut and sprung` over a groovedstud hvvhich vpasses through the nut into the shaft. vWith the hub Clthus `securely lafii'Xed to the shaft there may he attached thereto thering gear c 'or Vother part. The simplest ineans` for facilitating theattachment of the gear Vo to the huh d" is illustratech Whereinthe hub0l is provided With a cylindrical flange d' shouldered, as at (Z2, toafford asubstantial 'hearing surface for the inner periphery of thering` gear e; 'The flange OZ may have suitable bolt holes cl3 drilledand reamed therein Vafter the hub d" is aHiXed to the shaft-b andthrough these bolt holes Will pass the locking bolts c" whereby the gearc is held tothe Piange. It Will'he observed that the inner diameter ofthe ring gear o is such as to permit itto be passed over vthe spurpinion a in assembling` and disassenihling.

The improved, lgearing is defined in the accompanying claim in languagewhich will indicate the scope of the invention.

I claim as my invention v l'nA combination with a shaft, a pinion iii-Iteg'ral therewith'7 a flanged huh in juntaposiv tion to thepinionsupported onthe ,shaft and keyed thereto, said iiange beingformed. with' a shoulder on its innerface, anda ring `gear having' agreater internal diameter than.

the diameter of the pinion and a lesser internal diameter that` thediameter of the Y on said shoulder and holtedtosaid flange. 1 Thisspecification signed this 26th day of December A. D. 1919.
